The setting is stored for the remote control cur‐
rently in use.
Automatic headlamp control
Switch
position : the low beams are switched
on and off automatically, e.g., in tunnels, in twi‐
light or if there is precipitation. The indicator
lamp in the instrument cluster lights up.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
The low beams always stay on when the fog
lamps are switched on.
Personal responsibility
The automatic headlamp control cannot
serve

as a substitute for your personal judgment
in determining when the lamps should be
switched on in response to ambient lighting
conditions.
For example, the sensors are unable to detect
fog or hazy weather. To avoid safety risks, you
should always switch on the lamps manually un‐
der these conditions.◀
Daytime running lights*
With the ignition switched on, the daytime run‐
ning lights light up in position 0, or .
After the ignition is switched off, the parking
lamps light up in position

.
Roadside parking lamps The vehicle can be illuminated on one side.
Switching on
With the ignition switched off, press the lever
either up or down past the resistance point for
approx. 2 seconds. Switching off
Briefly press the lever to the resistance point in
the opposite direction.
Adaptive light control*
The concept
Adaptive light control is a variable headlamp
control system that enables dynamic illumina‐
tion of the road surface.
Depending on the steering angle and other pa‐
rameters, the light from the headlamp follows
the course of the road.
In tight curves, e.g., on mountainous roads or
when turning, an additional, corner-illuminating
lamp is switched on that lights up the inside of
the curve when the vehicle is moving below a
certain speed.
Controls
Activating
Switch position
with the ignition switched
on.
The turning lamps are automatically switched
on depending on the steering angle or the use
of turn signals.
To

avoid blinding oncoming traffic, the adaptive
light control directs light towards the front pas‐
senger side when the vehicle is at a standstill.
When driving in reverse, only the turning lamp is
active.
Self-leveling headlights
The self-leveling headlights feature adapts the
light distribution to the contours of the road.
The light distribution is lowered on hilltops to
avoid blinding oncoming traffic and tilted in de‐
pressions to increase visibility.
Malfunction
A Check Control message is displayed.

Adaptive light control is malfunctioning or has
failed.
Have the system checked as soon as pos‐
sible.
High-beam Assistant*
The concept
When the low beams are switched on, this sys‐
tem automatically switches the high beams on
and off. The procedure is controlled by a sensor
on the front of the interior rearview mirror. The
assistant ensures that the high beams are
switched on whenever the traffic situation al‐
lows. The driver can intervene at any time and
switch the high beams on and off as usual.
Activating the High-beam Assistant 1.
Turn the light switch to or .
2. Press the button on the turn signal lever, ar‐
row.
The indicator lamp in the instrument
cluster lights up.
When the lights are switched on, the
high beams are switched on and off automati‐
cally.
The system responds to light from oncoming
traffic

and traffic driving ahead of you, and to ad‐
equate illumination, e.g., in towns and cities. Switching the high beams on and off
manually
▷
High beams on, arrow 1.
▷ High beams off/headlamp flasher, arrow 2.
To reactivate the High-beam Assistant, press
the button on the turn signal lever.
System limits
Personal responsibility
The high-beam assistant cannot serve as
a substitute for the driver's personal judgment
of

when to use the high beams. Therefore, man‐
ually switch off the high beams in situations
where this is required to avoid a safety risk.◀
The system is not fully functional in situations
such as the following, and driver intervention
may be necessary:
▷ In very unfavorable weather conditions,
such as fog or heavy precipitation.
▷ In detecting poorly-lit road users, such as
pedestrians, cyclists, horseback riders and
wagons; when driving close to train or ship
traffic; and at animal crossings.
▷ In tight curves, on hilltops or in depressions,
in cross traffic or half-obscured oncoming
traffic on freeways.
▷ In poorly-lit towns and cities and in the pres‐
ence of highly reflective signs.
▷ At low speeds.
▷ When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc. Seite 86
